Edward S. Knotek II (2011) "Convenient Prices and Price Rigidity: Cross-Sectional Evidence" _Review_of_Economics_and_Statistics_ 93(3): 1076-1086.

* Data:

 - conv_prices.txt -- the raw data in a text file, this is loaded by MATLAB to produce the figures

 - n_values.txt -- a text file with values of n and nplus

 - convenience_data.xlsx -- a Microsoft Excel spreadsheet containing the relevant data for the regressions
	. Each row represents an observation
	. price is the price of the observation
	. conv is a dummy equal to 1 if convenience should matter and 0 if convenience should not matter for that observation
	. location contains a numerical location identifier
	. product contains a numerical product identifier
	. locationx and productx are the associated dummy variables
	. n and nplus are the level of relative inconvenience, as defined in the text
	. n1cent, n1percent, n5percent, n10percent are dummies taking on the value of 1 if the price is a monetary convenience point within a neighborhood of 1 cent, 1 percent, 5 percent, or 10 percent, respectively, using n as the measure of relative inconvenience, and 0 otherwise
	. nplus1cent, nplus1percent, nplus5percent, nplus10percent are dummies taking on the value of 1 if the price is a monetary convenience point within a neighborhood of 1 cent, 1 percent, 5 percent, or 10 percent, respectively, using nplus as the measure of relative inconvenience, and 0 otherwise
	. convpx is the interaction between conv and productx
	. nminus1 is relative inconvenience n minus one--used in the Poisson regression
	. nplusminus1 is relative inconvenient nplus minus one--used in the negative binomial regression
	. The key worksheet translates numerical codes to the establishment-type (location) and product groups listed in Table 1 of the paper

 - convenience_data.dta -- the same spreadsheet in Stata format for producing regression results

* Programs:

 - convenience_regressions.do -- a Stata do file that produces the regression results

 - convenient_prices_REStat_figures.m -- a MATLAB file that produces the data underlying the figures

 - fn_sort_p.m -- a MATLAB file called by convenient_prices_REStat_figures.m to sort the raw data

 - fn_freq_location.m -- a MATLAB file called by convenient_prices_REStat_figures.m to sort prices into bins for the figures

* Output:

 - stata_output.txt -- contains the output from running the Stata file convenience_regressions.do
